No I didn't.
I had a wireless mouse/keyboard set-up and had been using that. And during a re-boot I switched the TV with the remote to take a look at the news, like you do. And as the Pi boots it switches the TV source, ok but I was listening to the latest cricket or something, so I was switching back and forth, leyboard on my lap, remote in one hand, typing with the other.
It must have been a good 10 minutes before it dawned on me that I was using the remote on the RaspBMC too! Hadn't even thought it would work, so it was a bit of a surprise. 'Er in doors' now has that system to deliver music over in the West Wing, so its controlled via a web-interface and I've not investigated the ins and out of the way it works.
